the co-pending patent application titled Preiab- Y ricated Canopy for Toll Collection Booths, Serial No. 151,639, kiiled March 24, 1950. Y

Fixedv to the ends of the toll booths are the usual fare indication signal lights C, employed to indicate to, a customer or observer that a given toll transaction fare has been registered.` There is also shown wthe usual treadles, T, for counting the passage of vehicles through `the toll collection lanes,and a maintenance building M, which may house toll recording equipment and heat and light supply` facilities for thecollection booths. The roof e drainage systems embodied in this invention are supported on the canopy framework comprising a plurality of hollowl lateral girder members Il, Vtwo for each toll booth yandcne at the open end of the canopy, made of sheet metal and approximately" ysquare Vin cross-section. (Figs. 2v, 3, 46 and 7.) Bolted against ltheelends of saidlateral girderlmembers are hollow transverse girder membersiZ approximately .rectanguiar in crossfsection.Y v f f Lateral girder-members H adjacent the toll booths may loe-secured thereto as by angle irons I3, one-arm of which is Welded to said girder members .and the other arm of which is bolted asbyboltslll to thetop oi the toll booth (Fig. 4.-) Centrally-'located between transverse Y girder members I2 andXed-against the top of' lateral girder member Il, as by bolts I5, is a transverse channel ironmernber Iii (Figs.,2 and.4).

f The canopy A.roof comprises corrugated sheet metal Il mounted von transverse girder members l2 asby bolts it, andcentrally supported on thel top of channel iron member iii as by bolts 19 arrow, so .that water will flow along the grooves of the,corrugated-roofv Il into the drainage sys- Fig. 7 is a cross-sectional viewl takenvon linef5o tem at therrear end of thecanopy as hercinbelow described. A n

Transverse girder members l2 are surmounted byilashing membersf2 having upwardly and downwardlyextending 'ends and fixed to said girder members as "by-"self-tap-ping Ascrews 2i. There is"further"'provided, at the upper outer end of flashing member `20 side of said girder members, trim piece 22, curled over the upwardly extending end of hashing member 2U and fixed against the girder member as by self-tapping screws 23 (Figs. 5, 8 and 9).

Outer lateral girder member has welded against its ,top andflush with its outside face an angle iron-24 tojwhich is iiXed,1asby.self-tapping screw 26, trim pieceA 25, similar to said trirnA piece 22 (Figs. 4 and 7). There is welded against and along the inner side of angle iron 24 a plurality of U-shaped gutter brackets 23| adapted Vtosupport the drainage gutter 28. Said gutter re,- strained against upward displacementby off-set flashing piece 29 xed to trirnpiece2 5las -byV-syerlftapping screws 30. The upper end of trim piece 25 is curled over the upper end of said ashing piece. The outer end of transverse channel `iron member I has welded to it a short pieceof angle iron 3|, the top surfaceqf one arm of said angle iron being flush with the top surface of said channel iron member Y'for the purpose of supporting the outer end of sheet metal rooiing -l. It

should-be noted that angle irn 3| .andf'sheet metal roofing i? overhang the topfof gutter-28 so that water-'will drip into said gutter rather Athan seep below into the ycanopy structure. v`The "inner end or" transverse channel iron-.member 6 has welded to it a short piece of angle iron similar to angle iron 3|, the top surface of one arm of said angle iron being substantially iiuslf with the top surface of said channeliron member. Welded against angle iron 32 is a gutter bracket 33' adapted to support the drainage gutter 34. Said gutter communicates with and is further supported by the inner ends of front and rear drainage gutters 39 and lllfhereinbelow detailed. Likewise, gutter 28, hereinabove detailed, communicates with theouter ends of said front and reardrainage gutters (Figs. 4 and -5). i There is provided a recess inthe wall ofthe maintenance building in which isxed a channel iron 36 to'which vthe inner ends of the transverse girder members |2 areriixed. Said channel ironI is provided with 'flashing Amembers 35 Yand 31, the purpose of which -is Vto keep water conned to the top-of the canopy roof whereit may properly drain off. It should be noted that one 'end of hashing member 35 overhangs into gutter 34 so that water will drip into the gutter, rather than seepbelow and under the canopy.

Welded against the inner sides 'of the `front transverse girder member l2 are a plurality of drainage gutter brackets V38 adaptedlto vsupport U-shaped drainage gutteri.` It should be'noted that the downwardly extending end'of hashing U-shaped drainage gutter 4|.l

should be noted that the downwardly extending extends into said gutter.

Communieating with drainage gutter 4| v,at

points opposite the ends'of the 'tcll'booths are of the canopy, thereby compelling water in gutter l39 to flow down and around the outer end of the canopy into gutter 4|. Likewise, brackets 40 are vpositioned to pitch gutter 4| so as to drain into Aone ofthedrainage pipes 42.

Ihn'fthe.fmodification shown in Fig. 9, the corrugated ,sheet.metal roof is slightly bent in the center where it is fixed to transverse channel iron `member |15, so `that it inclines downwardly from theezenter toward the front and rear of the canopy as shown by the arrows. This modication provides for roof drainage at both the -frontandthe rear of the canopy. YTo this en d theiront gutter 46,supported by brackets `45, is provided at each booth with drain .pipes 41, iiexibie ooupimgs f4`a drain pipes 4 2,'one'for each booth, extending Yinto exible couplings'43" and thence intoconduits 44 extending into the toll booths for connection t9 the water disposal system.

It will now be Yevident from an inspection of Fig. 5 that, by Virtue of the downward inclina-Y tion of the roof towards the rear of fthe canopy, moet of .the freier Will .he califica i9 .the regret and conduits 49 similar to Vthose-abovementioned atthe rear of the canopy. Here again the gutters are preferably pitched-to drain into one of the pipes 4| so that .standing water cannot remain in the gutters. The operation of the modi'- edsystem is, of course, similar to that vvabove described `for drainage at the rear end of the canopy only. The use of the modiiied system is Apreferable in areas subject to heavy downfalis of rain.

-It will thus be seen Athat there is provided a roof drainage structure in whichthefseveral objects of this invention 'are achievedand which-is well adapted to meet the conditions of practical application.

As various possible embodiments might bevmade of the above invention, and as various changes might be made of the embodiment set forth, ,itis to be understood that all matters lhereinset forth or shown in the accompanying drawings'are'to be interpretedas illustrative and not in a limiting sense.
